How can I get the Aviator game on my phone in India?

Hi everyone, I'm new to online games and really like the Aviator crash game. I see many people playing it on mobile in India. Is there a simple way to play it on my Android phone? I have a Samsung device with Android 11. Do I need a special app or can I just use the browser? Also, is it safe and legal here? Some sites look suspicious. Can someone explain the best steps to start without issues? I want to try demo first if possible.
